　　jersey 配置类

/**
 * 配置 jersey rest api 资源路径, Spring Boot建议在使用
 * ResourceConfig添加资源类的时候，不要使用packages方法去自动扫描，建议还是使用register添加。
 * 
 * 注解ApplicationPath，默认为/*
 * 
 */
@Component
@ApplicationPath("/jersey")
public class JerseyConfig extends ResourceConfig  {
    
    public JerseyConfig() {
        //packages("com.oy"); // 扫描 com.oy 包，使其识别 JAX-RS 注解
        register(UserController.class);
